Specification of Letters Patent.

Patented July 25, 1916.

Application filed January 8, 1916. Serial No. 70,899.

13, 1910, Serial No. 581,748, wherein are dis-v closed certain featuresin relation to `such spindles which are also preferably incorporated inthe structure shown herein.

The present object is to further improve these spindles, securing asimple, substantiel and relatively `light construction, easy tomanufacture and adapted to utilize the principle of balanced masses setforth in my said prior application, and especially to produce a spindlein vwhich the operation'of threading up can be, accomplished withrapidity. j

In the accompanying drawings: Figure 1 is a view, partly in sideelevation and partly in longitudinal section, of the spindle, with itshauling-ofmechanism and flier, and the associated bobbin and bobbinspindle; Fig. 2 is a view', also partially in elevation and partially inlongitudinal section, taken at a different angle from Fig. 1; and Fig. 3is a cross-section onthe line III of Fig. 1.

- The body of the spindle is a substantially straight shaft l, which, asa matter of design, may vary in cross-sectional area and shape atdifferent points in its length. Its separated portions 2 and 8, adjacentthe ends are formed as journals to turn in the bearings 4. and 5, whichare carried by thev fixed framework of the spinner, not shown. The endportion of the-shaft comprising the journal 2 is tubular'and aords aninternal bearing for an independently driven yarntube 6, which projectsbeyond the bearing f1 and beyond the end of the spindle and is I. thereprovided with ay gear 7 whereby it is rotated independently `and at aspeed differing from that of the spindle, which is driven by a pulley 8mounted adjacent-the ournal 2. rlhe portion of the shaft constitutingthe other journal 3 is of largerl diameter than the -journal 2 and isenlarged outside the bearing 5 to form an end thrust shoulder 9 and aface plate or flangelO, to which latter the base of a can Hier is firmlybolted or otherwise secured.

- f Intermediate its journal portions and the supporting bearings, theshaft carries the hauling-off mechanism which comprises main andauxiliary capstans 12 and 13, each mounted to revolve on an axisintersecting and transverse to the aXis of the spindle. As in my priorapplication/aforesaid, the capstan members arel constructed so as tohave equal portions of their mass disposed at opposite sides ofthe aXisof the spindle, whereby the benefits of high speed operation may berealized, as there fully explained. rl`he capstansA proper, however,andtheir counterbalancing elements are at opposite sides of the spindlebody, that is to say, on opposite sides of the immediate supportingportionof the spindle, which is in line with the-journal portionsinstead of olf.

set therefrom as in my prior construction.

The capstan 12 is Xe'd on an axle 14 which is journaled in a transversebearing bored in the spindle body and carries at its opposite end Yabevel gear 15, which is dished or crowned in order that its teeth maymesh with the teethof a bevel pinion 16 on the inner end of theyarn-tube 6, the engage* ment of the toothed members being made possibleby a clearance groove in the shaft at this point, as will be Vseen in FigfS. The counter-balance for the auxiliary capstan 13 comprises acap-like washer 17 interposed between the nut 18 on the end of thecapstan axle 19 and a boss 20 on the spindle, it beoil' masses is notessentialto the invention;

The sliver which enters through the tube 6, on the dot-and-dash lineindicated, passes beyond this tube through a passage 21 in the interiorof the shaft, the said passage bearing off oblquely or at a gentlecurvature from a general longitudinal direction, in order to conduct theslivery in a. substantially straight-line path to a lateral,obliquelyfacing outlet 22, between the axes of the two capstans andsubstantially opposite the grooved periphery of the auxiliary capstan13, to which the incoming stretch `of yarn directlyextends. Thence theyarn'is trained Vback to the main, or positively driven, capstan 12, andthence back and forth between the two for a suitable number of passes,according to the number of yarn grooves provided therein, after which itis trained over an external guide pulley 23, adjacent and at the innerside of the bearing 5,y and between the hauling-olf mechanism and theflier. This guide is counter-balanced like the capstan 13, having aVstern 24: which is inserted through a diametrical hole in the spindleand provided at the otherside thereof with a cap or washer 25 and nut26. From the guide button23 the yarn passes through a transverse andstraight passage 2f( extending the open end of the ier, and thencepasses,

inward to the bobbin 30, the guides 28 and 29 on the iiier being`preferably in skewedv relation as shown in order tcsecure the advantagesset forth in ymy prior application before mentioned. The bobbin it vwillbe understood, is traversed by suitable mechanism, not necessary toillustrate, on the bobbinspindle 31, one end of which finds a terminalbearing at 32 in the endl face of theA flier spindle.

The mounting of the yarn tube 6 in the feeding-in end of the flierspindle, includes Va bushing or internalsleeve 33, which is threaded asshown at 311 to the Yinterior of the outer end of the tubular portion ofthe spindlebody, the outer end of this bushing having a flange 35 inabutting relation to the extremity of the spindle, and its inner endpreventing outward axial movement of theV pinion 16 and therefore oftheyarn tube.

It will be evident that the through passagevr27 together with theexternal location of the pulleys and the fact that there need befbut onedirection-changing guide on the spindle between the hauling-offmechanism and the flier, greatly increase the ease and quickness withwhich the threading operation may be performed. In this connection it isto be observed that the course of the yarn from the inlet end of theyarn tube 6 to the lateral outlet 22 is substantially aV straight one,and that the capstans .are wholly exposed and devoid of adjacentobstacles to the` hand or yarn in threading, thesebeing matters of muchpractical importance to the operator, in respect to the time saved andthe wear on the machine, by

the yarn, and the wear on the yarn by the machine.

What I claim as new is 1.
